Growing conditions
It tolerates full shade. USDA rates it as having low water needs once established. Its drought tolerance is rated medium. It is recorded on soils from pH 4.3 to 6.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 4.
Size and growth
At maturity it reaches about 1.4 ft, making it a low, mat-forming plant. It grows slowly.
Bloom period
USDA records a bloom period of May through June. Flowers are white.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is green, medium in texture. Its flowers are conspicuous. Its active growth period is spring and summer. USDA rates its lifespan as long.
What the site needs to provide
USDA records it across sites receiving 28 to 60 inches of annual precipitation. It needs at least 180 frost-free days to finish its season. It roots to at least 14 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.
Propagating it
Propagate it from seed, bare root and container stock. Seed needs cold stratification — a period of moist chilling — before it will germinate, so sow in autumn or chill it artificially before a spring sowing. Its seed spreads at a slow rate. It spreads vegetatively at a moderate rate.
Resilience and wildlife
Browsing animals find it moderately palatable, so expect deer and rabbits to take an interest. Its fire tolerance is rated high, and it can resprout after damage. Its growth form is recorded as rhizomatous.
Role in a guild
Ground cover. In a layered planting this is the lowest layer — it shades soil, holds moisture, and suppresses weeds. The layer is derived by a fixed rule from growth habit and mature height.
